Metadata schema registries have great potential to enhance usability and reusability of metadata schemas. Application profiles are a key concept for Dublin Core, and have a crucial role in promoting reuse of metadata schemas. This paper discusses basic concepts and models of metadata schemas, in order to clarify functional requirements for extending registry functions to enhance usability and r...

Medical Cyber-Physical Systems (MCPS) are context-aware, life-critical systems with patient safety as the main concern, demanding rigorous processes for validation to guarantee user requirement compliance and specification-oriented correctness. In this article, we propose a model-based approach for early validation of MCPS, focusing on promoting reusability and productivity. It enables system d...

Routing metrics are essential to achieve a good end-to-end throughput on a min-cost path in multi-hop wireless networks. Originally, most routing algorithms were based on min-hop count metric. Then link-quality aware metrics, ETX and ETT, are proposed. After that, the emergence of opportunistic and any-path routing, leads to metrics such as EOTX and EAX. But almost all the previous routing metr...

Reuse techniques are key for the industrial adoption of ModelDriven Engineering (MDE). However, while reusability has been successfully applied to programming languages, its use is scarce in MDE and, in particular, in model transformations. In previous works, we developed an approach that enables the reuse of model transformations for different meta-models. This is achieved by defining reusable...

The need for easy, non-technical interfaces to clinical databases for research preceded translational research activities but is made more important because of them. The utility of such interfaces can be improved by the presence of a persistent, reusable and modifiable structure that holds the decisions made in extraction of data from one or more datasources for a study, including the filtering...

This paper presents E x Claim, a hybrid language for knowledge representation and reasoning. Originally developed as an operationalization language for the KADS knowledge based systems (KBS) development methodology, E x Claim has a meta-level architecture: it structures the knowledge on three levels, namely the domain, inference and task level. An extension of a description logic is used for im...

This paper describes how to improve the reusability of iconic program modules. In iconic programming systems, the most important features for reuse are the customization of a module and combination of multiple modules without changing their definitions. In order to realize these features, we propose an object sharing technique, which allows components of multiple modules to represent the same o...

In this paper we investigate the implications of Java’s dynamic proxies for supporting open architectures to implement reusable code. Dynamic proxies are interpreted as meta-objects, which define the behaviour of other objects and allow the implementation of meta-objects protocols.

1 Introduction Substantial formal grammatical and lexical resources exist in various NLP systems and in the form of textbook specifications. In the present paper we report on experimental results obtained in manual , semi-antomatic and automatic migration of entire computational or textbook descriptions (as opposed to a more informal reuse of ideas or the design of a single "poly-theoretic" rep...

two simple protocols for the synthesis of tetrahydrobenzo[a]xanthenes-11-ones using nano silica phosphoric acid are reported. short reaction times, high yields, reusability of catalyst and easy workup are some advantages of these protocols.
